P0Adb Fault Code: Understanding The Causes And Solutions
The P0ADB fault code refers to a problem with the Hybrid Battery Positive Contactor Control Circuit. This circuit is responsible for connecting and disconnecting the high-voltage power supply in the hybrid vehicle. The circuit consists of three relays, with two on the positive side and one on the negative side.
When connecting, SMR1 and SMR3 turn on first, followed by SMR2. This process protects the circuit from high-voltage surge current.
When disconnecting, SMR2 and SMR3 turn off in that order.
The HV control ECU checks that the relays have turned off properly. If the HV control ECU detects a malfunction in the SMRs (CON1, CON2, and CON3), it will trigger the P0ADB fault code.
This code indicates that there is a low voltage issue in the Hybrid Battery Positive Contactor Control Circuit.
FAQ
